Help...a PO removed rear tank left

[seefriedm]

A PO dropped the rear tank, and left it in the bed of the truck. I am getting ready to install it today and need some help/picture if how to hook up the two tanks through the selector valve in front of the rear tank. It has looking from the front an one opening on the drivers side and two on the passengers side. I've tried blowing through it and using the selector on the heater panel to try to determine which goes where, but not much luck. Are you able to help?

Mil1ions,
Thank you for the assist. I do notice sometimes folks playgerize other folks work. I believe credit should go where credit is due. Some folks on the other site might not know about this one and Steponit is filling in the missing info and helping them out.

The hookup is largely idiot proof, in that the hose sizes are different to prevent being hooked up wrong, and the plug only goes one way as well.

Thanks Dennis for the help. I got the tank in and valve connected with no problems. Went to put gas in and everything worked as advertised. The diagrams were great. Now on to troubleshooting why the center (main) tank reads different (lower) than the rear tank on my gas guage, any suggestions? Niether go to the Full.

It could be grounding issues, could be a float that has a pinhole, allowing gas into the float a little, which then makes it sink.

I used the brand new sending unit for the center tank to test each of the 2 connectors. I haven't checked the grounds out yet. I might just short the two connectors to see if that gives the same reading short the one to ground and see if it changes the position on the gauge.
